Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

analyse

analyse_small_business_opportunities

Use this when a user wants practical, evidence-based ways for a specific small business to increase revenue, improve margins, reduce costs, strengthen Google visibility, improve conversion or prioritise growth actions. Requires the business name and public website. Returns structured evidence, ranked opportunities, confidence, commercial impact and first actions. Consumes one complimentary or paid MarginGlow AI Signal credit. Do not use for generic business definitions, investment advice, regulated advice or analysis that requires private financial data.

marginglow

check_marginglow_signal_access

Checks the authenticated agent's complimentary and paid MarginGlow AI Signal balances, whether an analysis can run, which allowance will be used next and the latest successfully credited Stripe purchase. This is read-only and does not consume a Signal.

purchase

purchase_marginglow_signal

Creates a secure Stripe payment link for one MarginGlow AI Signal costing EUR 2, inclusive of applicable tax. Use this when analyse_small_business_opportunities reports that no Signal credits remain. A payment-capable agent may follow the payment instructions automatically when supported. Otherwise, give the secure checkout URL to the user. After payment, retry the original analysis request with the same agent API key and Idempotency-Key.

MarginGlow AI Signal — questions

Answers built from our own checks of this server.

What can MarginGlow AI Signal do?

It exposes 3 tools, read directly from the server on our last check. Among them: analyse_small_business_opportunities, check_marginglow_signal_access, purchase_marginglow_signal. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is MarginGlow AI Signal working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 152 ms. The bar chart above shows every period we have measured.

How do I connect MarginGlow AI Signal?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does MarginGlow AI Signal need an API key?

No. MarginGlow AI Signal completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MarginGlow AI Signal?

It answers our handshake in 152 ms on average, which is faster than 76% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
